On Dissociative Behaviour
(from Chapter LXXXI, Seven Pillars of Wisdom, Penguin paperback edition.)
25 November 1917, 4 days after Deraa
Auda is unable to supply them with fresh camels when they arrive at his camp near Jefer in the forenoon.
“… now I was nearly finished. Step by step I was yielding myself to a slow ache which conspired with my abating fever and the numb monotony of riding to close up the gate of my senses. I seemed at last approaching the insensibility which had always been beyond my reach: but a delectable land: for one born so slug-tissued that nothing this side fainting would let his spirit free.
Now I found myself dividing into parts. There was one which went on riding wisely, sparing or helping every pace of the wearied camel. Another hovering above and to the right bent down curiously, and asked what the flesh was doing. The flesh gave no answer, for, indeed, it was conscious only of a ruling impulse to keep on and on; but a third garrulous one talked and wondered, critical of the body’s self-inflicted labour, and contemptuous of the reason for effort.
The night passed in these mutual conversations. My unseeing eyes saw the dawn-goal in front; the head of the pass, below which that other world of Rumm lay out like a sunlit map; and my parts debated that the struggle might be worthy, but the end foolishness and a re-birth of trouble. The spent body toiled on doggedly and took no heed, quite rightly, for the divided selves said nothing which I was not capable of thinking in cold blood; they were all my natives. Telesius, taught by some such experience, split up the soul. Had he gone on, to the furthest limit of exhaustion, he would have seen his conceived regiment of thoughts and acts and feelings ranked around him as separate creatures; eyeing, like vultures, the passing in their midst of the common thing which gave them life.”
Poor Ned, what he describes in that short passage sounds very much like this:
What Is Dissociative Identity Disorder?
Dissociative identity disorder is a severe form of dissociation, a mental process which produces a lack of connection in a person's thoughts, memories, feelings, actions, or sense of identity. Dissociative identity disorder is thought to stem from a combination of factors that may include trauma experienced by the person with the disorder. The dissociative aspect is thought to be a coping mechanism -- the person literally shuts off or dissociates himself from a situation or experience that's too violent, traumatic, or painful to assimilate with his conscious self.
There are several main ways in which the psychological processes of dissociative identity disorder change the way a person experiences living, including the following:
Depersonalization. This is a sense of being detached from one's body and is often referred to as an "out-of-body" experience.
Derealization. This is the feeling that the world is not real or looking foggy or far away.
Amnesia. This is the failure to recall significant personal information that is so extensive it cannot be blamed on ordinary forgetfulness. There can also be micro-amnesias where the discussion engaged in is not remembered, or the content of a meaningful conversation is forgotten from one second to the next.
Identity confusion or identity alteration. Both of these involve a sense of confusion about who a person is. An example of identity confusion is when a person has trouble defining the things that interest them in life, or their political or religious or social viewpoints, or their sexual orientation, or their professional ambitions. In addition to these apparent alterations, the person may experience distortions in time, place, and situation.
There is of course even more to this. The article under the following link is a lot longer:
